How do we know the doctrine of Christ's satisfaction is true?

Christ's satisfaction is foundational to understanding the extent of His atoning work for believers. In Song of Solomon 5:1, the imagery of Christ consuming and enjoying the fruits of His garden symbolizes His complete satisfaction with the sacrifice He made for His people. This satisfaction is confirmed in Acts 4:12, which states that salvation is found in no one else but Jesus. He accomplished everything necessary to make us acceptable before God through His righteous life and sacrificial death. Believers can confidence that they do not need to add to His work; His provision is sufficient and perfect, satisfying God's justice on their behalf.
